Hi zombie, I have sent the email, I think I got it right, (computers are a bit of a mystery to me).I tried to drill into the slide a little to adjust the pin, it did make a difference but so slight. I resoldered the jet and got it to about 0.85mm, it is rideable so I held it full open and took the plug out when I got back, (didn't take the tool kit with me, was still sitting in the shed from having the bucket out). I took some photos of the plug, but again they are not much good.
